Honest Illusion

Another week, another C# interview question from the good folk's at Dev102.com -- Although I use the term ''good folks'' advisedly, as this week they did not even acknowledge the solution I posted for last weeks puzzle (which was both correct, and, I believe, the first blog post about it). Anyway, time to move on to this week's question. ...

The folks at Dev102.com are offering weekly programming challenges, where they offer questions, and let bloggers post about them.  I meant to write an answer for last week, but never got around to it.  Just as well -- my answer would have been wrong.  SO, let's move on to this week's: How would you implement the following method: Foo(7) == ...

Today, either Bloglines.com or blogs.MSDN.com blinked, and suddenly I'm seeing old entries on the 'C# Frequently Asked Questions' blog as new.  No one has posted anything there in over two years. Anyway, reading the most recent message, it offered a method for logging a message.  Now, ignoring side debates over log4net vs nLog vs. the Event ...

Recently I was looking at some C# code where the author, to loop through some collection,  would frequently use call GetEnumerator() and the manually step through the collections, calling MoveNext().  It seemed to me that the code could be written more cleanly using a foreach.   I got to wondering it the author knew some funky optimization ...

(Note: I started writing this a couple days ago --- a short while before Andrew Matthews published his own very similar article.  He, of course, finished his first...) (Update: Fixed the spelling/grammar, and then wrote a bit more) Lately on some of the blogs I read, I've been seeing  people giving code implementing various Design Patterns.  ...

As I was reading this article by Granville Barnett on some of the new operators available on LINQ queries, I thought, ''That's all well and good, but for the time being, we're living in a .Net 2.0 world.  I wonder if I could emulate those with just generics & iterators?''  As it turned out, it was quite easy. First up is Take:  Given a ...

Many years ago, I wrote an article entitled ''Implement A Circular Iterator'' for The VisualC++ Developer's Journal.  (Unfortunately, VCDJ is now out of business, and it's successor, Visual Studio Magazine, doesn't maintain an online archive of articles from that magazine.  Fortunately, I kept a copy of it) The essence of the C++ code is that ...

Here's the C# source code for my SkipFirst Modifier for foreach().  Detailed description here

A couple years back, I made a proposal online for a new feature in C#.  It gathered some interest in the newsgroup.  I later emailed it to someone on the C# team at Microsoft (I believe it was Eric Gunnerson but I'd really have to look it up), who emailed back a very nice response saying basically, ''We thought about something like this, but ...

Here's the source code, project file and PowerPoint file for my presentation at the 3rd NJ Code Camp.
